SlickFlow: Intelligent Workflow Automation with Large Language Models
SlickFlow now integrates cutting-edge Large Language Model (LLM) nodes, empowering your workflows with advanced conversational reasoning and intelligent automation capabilities. This enhancement transforms traditional workflow systems into dynamic, AI-driven orchestration platforms.

🚀 Key Features
🤖 Native LLM Node Integration
Seamlessly incorporate LLM nodes directly into your workflow diagrams. Configure and connect AI-powered steps alongside traditional business logic for end-to-end intelligent automation.

🔌 Multi-LLM Provider Support
Flexible integration with leading AI services:
OpenAI API​ (GPT-4, GPT-3.5, and beyond)
QianWen​ (Alibaba's large language model)
Extensible architecture for additional providers

Image Classification & Analysis:
Upload and process images directly through LLM nodes

Retrieval-Augmented Generation (RAG):
Enhance LLM responses with real-time data retrieval from your knowledge bases

AI Image Classification Process Demo:

Quick Start Tutorial for Designer Project:
1). In the command console, using the command npm install to download the node package.

please notice to run the command, the directory location is in the ClientApp path of the sfd project.

2). Set up the sfdapi project which is an asp.net webapi type project.(IIS is a choice)

3). Setting webapi variable in the kcofnig.js file

kconfig.webApiUrl = "http://localhost/sfdapic/" //your sfd webapi backend service url

4). In the command console, using the command npm run dev to the the project

5). Access the web project in the browser by

**http://localhost:5000**

.NET8 Workflow Engine With Full Source Code

0. Deepseek/QWen-Plus AI service supported
   Slickflow can use AI deepsesk service to generate BPMN flow chart through text description by users. Large model nodes also participate in business processes as intelligent nodes in the process sequence, completing the functions of intelligent generation and intelligent decision-making
1. .NET, Cross platfrom development
   Slickflow is an open-source project based on .NET8; It's easy to use engine product into the cross-platform application, such as Linux, MacOS
2. BPMN graphic style process diagram
   Slickflow is using BPMN2 notation to describe process diagram, the Slickflow designer is HTML5 graph editor and user-friendly to business process communication and business analysis.
3. High performance with Dapper.NET library
   Dapper is a simple object mapper for .NET and owns the title of King of Micro ORM in terms of speed and is virtually as fast as using a raw ADO.NET data reader. An ORM is an Object Relational Mapper, which is responsible for mapping between database and programming language. (Ref: https://dapper-tutorial.net/dapper)
4. Multiple databases supported
   Slickflow supports SQLSERVER, ORACLE, MySQL and another database, it implemented by the Dapper.NET extension library. The .net core version using EF core to support different database products.
5. Workflow patterns supported
   
   1). Sequence
   the most frequently process pattern
   2). Split/Merge
   support and/or gateway such as and/or split, and/or join, together with condition variables on the transition
   3). Sub-process
   in the main process, a subprocess node can start a new process life cycle.
   4). Multi-instance
   multiple performers processing a task together by multiple task instances. All performers both compete for their task, then the process can be continued on. There are sequence and parallel pattern, and the percentage or count parameters can be set on it to ensue when can go to the next step.
   
   5). Event interoperation
   process instance and activity instance event delegation service, such as process/activity start, execute and complete.
   6). Timer
   integrated with HangFire library, and with CRON expression supported
   7). Email
   todo or overdue tasks email notification
   8). Withdraw
   withdraw the task after just sent out to next step users.
   9). Sendback
   send back to the previous step user, because of some exceptions.
   10). Resend
   combined after sendback and re-send the task to original sendback users.
   11). Reverse
   reverse the process instance alive when completed.
   12). Jump
   jump the process over by several steps forward or backward.
   13). MessageQueue(RabbitMQ)
   message publishing and subscribing to implement message throwing and catching.

6. Process Version
the process has version property to upgrade a new definition due to the business process changed.
7. XML Cache
the runtime instance use cache to keep the XML process diagram by an expired duration.
8. Sequence Process Code Style
0). Model

//create a simple sequence process diagram by hand code rather than a HTML designer  
var pmb = ProcessModelBuilder.CreateProcess("simple-process-name", "simple-process-code");
var process = pmb.Start("Start")
	.Task("Task1")
	.Task("Task2")
	.End("End")
	.Store();       

1). Start

//start a new process instance
IWorkflowService wfService = new WorkflowService();
var wfResult = wfService.CreateRunner("10", "jack")
            .UseApp("DS-100", "Book-Order", "DS-100-LX")
            .UseProcess("PriceProcessCode")
            .Start();

2). Run

//run a process instance to next step
IWorkflowService wfService = new WorkflowService();
var wfResult = wfService.CreateRunner("10", "jack")
            .UseApp("DS-100", "Book-Order", "DS-100-LX")
            .UseProcess("PriceProcessCode")
            .NextStepInt("20", "Alice")
            .Run();

3). Withdraw

//Withdraw a activity instance to previous step
IWorkflowService wfService = new WorkflowService();
var wfResult = wfService.CreateRunner("10", "Jack")
            .UseApp("DS-100", "Book-Order", "DS-100-LX")
            .UseProcess("PriceProcessCode")
            .OnTask(id)             //TaskID
            .Withdraw();

4). SendBack

//Sendback a activity instance to previous step
IWorkflowService wfService = new WorkflowService();
var wfResult = wfService.CreateRunner("20", "Alice")
            .UseApp("DS-100", "Book-Order", "DS-100-LX")
            .UseProcess("PriceProcessCode")
            .PrevStepInt()
            .OnTask(id)             //TaskID
            .SendBack();

9. Rich demo projects
WebDemo, MvcDemo, and WinformDemo project are demonstrated for a different type of enterprise information systems.
